"So Sarah conceived and bore a son to Abraham in his old age, at the appointed time of which God had spoken to him." (v.2)
Sarah's wait had been long and hard. It was so difficult, that she had given up any hope long ago that she would ever have a child. But, here she was, ninety years of age, baring a son to Abraham in his “old age” (100 years), just as God said. And, it was precisely at the time God had specified it was to happen.
Our God is full of miracles. When He "speaks" to you, whether through His Word, in a dream or directly to your waking heart, take the risk of prayerfully responding to His plan for your life. Abraham did, and it led to this moment when he actually received the promise of God. You may think that having a son is not a miracle, but Abraham and Sarah would argue that point with you. This was their child of the promise and he knew unmistakably that God had brought this moment, this boy, into Abraham's and Sarah's lives.
I would venture to say that most of us have unrealized hopes in this life. Maybe to the point that you may feel the Lord has not been listening, that He has forgotten you or that He has placed a promise into your heart that has not become real in your life. Have faith in God - even though your ability to believe that God can and will do ANYTHING may be limited, His power is not.
Both Abraham and Sarah had at first laughed in disbelief at the promise of God. In Genesis 17:17, we see that Abraham "fell on his face and laughed" when God promised him a son. "Sarah laughed to herself" about this promise, as seen in Genesis 18:12. Proof, that our God loves to go above and beyond that which we could ever ask or think.
Therefore, if it seems like God is slow in fulfilling the promise in your life, even if it seems impossible to the point of laughter, wait. Wait hopefully and expectantly, and He shall give you the desires of your heart.
The Truth: “Delight yourself in the LORD, and He will give you the desires of your heart. Commit your way to the LORD; trust in Him, and He will do it.” (Psalm 37:4-5)
